Performance during pathogen challenge

Whether maximum performance is achieved depends on the composition of the feed and the environment in which the pig is kept. But how is the feed intake and thus growth and performance influenced when pigs are exposed to infectious pathogens? Ilias Kyriazakis gives us an insight. When pigs are exposed to pathogens, the animals often show a (temporary) reduction in feed intake, henceforth called anorexia. Sandberg et al. (2006) have proposed that there are at least two functional mechanisms t
